I had a 95 F-150, and it used no oil, even at 120k. I just changed oil
every 3,000. Only time it "used" oil was when the oil galley seal leaked
on the straight six block.

My 2001 Focus is tight as well, and I am at 92K.

I used to use synthetics, but they don't seem to be any better for
engine oil. Perhaps regular changes every 3,000 to 6,000 miles will do
everything the synthetics will do, and at less than half (or a quarter)
of the cost.

I have been changing oil every 20,000 to 50,000 miles in my cars since
1975, using synthetic oil. I change filters with every oil change.
We have never had an oil pan or head off any car, nor has the gas
mileage gone south before we traded them in or moved them down the line to
relatives. The first car to get this treatment was a 1975 VW rabbit
(traded at 120,000) and the latest is a 1992 Nissan Sentra with 306,000
miles on it, still getting about 3500 miles to the quart of oil at
present.
